Awesome innards of this reflective LCD system. Light from the main bulb comes in bottom, is diffused and split two ways by a double beam splitter, filtered, polarized, split again on left branch, producing 3 uniform channels of vivid red, green, and blue light. Each channel enters a prism, reflecting off an HD LCD element bonded to the back surface of each prism, after which each channel is directed by its respective prism towards another double beam splitter that combines all three channels into one image, and then sent to a short throw projection lens with a 90 turn. It was fun to tear down. The LCD prisms, beam combiner, and projection optics were mounted to a common cast metal chassis to keep alignment. Loads of special coatings on all the glass, and cool reflections. We played with the parts for hours last night.
